CLOCK STRIKING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 403,275, dated h'Iay14, 1889.

Application filed August 13, 1838. Serial No. 282,5i6. (No model.)

To all whom it may concern.-

Be it known that l, ALMERON M. LANE, a citizen of the United States,residing at Meriden, in the county of New Haven and State ofConnecticut, have invented certain new anduseful Improvements in Clocks,of which the following is a specification.

My invention relates to improvements in clocks which have strikingmechanisms; and the objects of the improvement are to enable thestriking mechanism to be mounted outside of the clock-case in aneat andattractive form, and also to connect the striking mechanism with thetimennovement in a convenient and eflicient manner, and so that they maybe easily detached for repairs.

In the accompanying drawings, Figure 1 is a partial vertical section andpartial elevation of my clock, the plane of section extending at rightangles to the center shaft. Fig. 2 is a partial vertical section of aportion of said clock, the plane of section extending through the axisof the center shaft and Fig. 3 is a horizontal section of the base andplan view of the striking mechanism with the top plate removed.

A designates the cloolvcase, containing within it a time-movement of anyordinary construction, said case being mounted upon a base, B, whichcontains within it a striking mechanism, 0, of any ordinaryconstruction. Upon the center shaft, 4, of the timeanovement I arrange acam, 5in the present instance having two arms or shoulders, so as tooperate the trip inng-lever every half-hour, the striking mechanismbeing adapted to strike the halidrour as well as the hours of the day.In case a striking mechanism is employed which does not strike thehalf-hour, then the cam 5 would be provided with only one arm orshoulder.

Upon one of the time-movement plates 1' mounted upon the shaft 8, fromwhich extends an arm, 9, the end of which is bent upwardly and passesthrough openings into the clockcase A to a point by the side of thelower end of the lever 6, as shown in Figs. 1 and 2.

The cam 5, revolving in the direction indicated by the dart in Fig. 1,strikes the upper end of the lever 6, thereby pressing its lower endagainst the rigid arm 9, which extends from the warning-wire '7, andpresses said arm to one side, thereby forcing the hook out of the notchin its cam 11 and bringing the hook 12 into position to engage the pin13, and thereby prevent the wheel upon which said pin is mounted frommoving farther until the upper end of the lever 6 drops off the shoulderof the cam, thereby releasing the warning-wire and permitting the strikemechanism to operate in the ordinary manner.

All of the parts of the striking mechanism are old excepting the rigidarm 9, which extends upwardly into the clock-case t0 the lever 6, whichlever, in connection with the cam 5, forms a strike-tripping mechanism.

I am aware that in some striking mechanisms the warning-wires, &c.,which are usually termed the loclework, are arranged to fall intoposition by gravity, while in other striking mechanisms they arespring-actuated, so as to be operative when the clock is in anyposition. The lock-work must be spring-actuated when it is set with theplates of the striking mechanism in a horizontal position, as shown inthe drawings.

A prior patent shows and describes a clock having a cam and drop leverwithin its case and a bell-striking apparatus outside said case forstriking a bell capable of being heard miles distant by the action of aclock of small size. A cord extends from the drop-lever within theclock-ease to a drop-lever near the bellstriking mechanism, the latterdrop-lever being provided with a spring-pressed toothed pawl, whichholds other levers, some of which are spring pressed and one of which isnotched to hold and release an arm that ex tends from a shaft somewhatanalogous to the warning-wire of a clock striking mechanism. These lastmentioned lovers with their springs, notches, and toothed pawl are outside of the clock case and are essential parts of the trippingmechanism. The arm which extends to this tripping mechanism does notenter the clock-case or even extend to a point near said clock-case.Such aclock and bell-striking mechanism is hereby disclaimed.

I am also aware that ordinary alarm-clocks have been made with aseparately-constructed alarm mechanism set below the time mechanism andconnected by a wire or cord, one end of which was attached to an armthat projected from the pallet of the alarm mechanism and the other endattached to atrip-lever on the time mechanism, and that a prior patentshows this ordinary alarm-clock with the time and alarm movement inseparate chambers. Such alarm clocks are hereby disclaimed.

I claim as my invention 1. The herein-described striking-clock,consisting of a clock-case, a time-movement having a strike-trippingmechanism within said case, and a striking-movement outside said casehaving a rigid arm extending from the warning-wire to a point by theside of the tripping mechanism within the clock-case, substantially asdescribed, and for the purpose specified.

2. The combination of a clock-case, a timemovement within said case, thecam 5, attached to and moving with said, time-movement, thetripping-lever 6, having one end in engagement with said cam and thestriking mechanism separate from the time -movement and having an armdisunited from said lever and extending from the warning-wire to a pointby the side of theother end of said lever, substantially as described,and for the purpose specified.
